If the distance between two bodies is doubled the gravitational force will:
Correct answer: D. Become one fourth
- A. Remain same
- B. Become four times
- C. Increase four times
- D. Become one fourth
Explanation
F=GMm/R2 When the distance is doubled, F'= GMm/4R2On comparing both the forces their ratio is equal to F'/F= 1/4Hence the correct option is D.

About Gravitation
Newton’s law of universal gravitation relates the force between masses to their masses and separation, while gravitational field strength explains weight and orbital motion. The topic covers satellite velocity and period, escape ideas, weightlessness in free fall, and artificial gravity, which differs from ordinary gravitational attraction.
